This is the second time this has happened. I have disabled mouse acceleration on Ubuntu by following these instructions.
Immediately after that I tried to log out but the system got hung at the fsck screen, so after about 5 mins I force-shutdown the system and when turning it on again Ubuntu got stuck on the fsck screen and won't get past that!
I have tried using a live USB to both delete the file that I created and also run fsck on the sda6 partition and it says everything is OK. Don't really know what to do now. This is what it looks like:

After experiencing this exact same issue, using Ubuntu 16.04.02, I found a couple of ways to work around it. It seemed my problems were caused by changing the graphics nvidia drivers, and although I haven't found a way to properly work the drivers, I can get the regular login operation working again.
First Fix.
GRUB
.ubuntu
boot command, I added the commandnomodeset
to the line starting withlinux
, just before other commandsquiet splash
. See this for an example.sudo apt-get purge nvidia*
to remove the unusable graphics drivers. Can be installed again later if need be. (ie, here)Second Fix (Context: After achieving sucess with the first method, I proceeded to reinstall nvidia drivers to attempt to get the working again. Doing so, I also restarted
xserver
as described here which ended up breaking my login process, and even withnomodeset
still resulted in the same issue.) Looks like the GIF in this.GRUB
. SelectAdvanced options for Ubuntu
.Root
option to drop to a root shell prompt.sudo apt-get purge nvidia*
to remove the unusable graphics drivers.xserver
dependencies. This is because xserver hosts nouveau drivers for graphics cards.You should now have regular access to your Ubuntu instillation, but I can't comment on your graphics card functionality.
